connectors are in the same order as the indicator LEDs when viewed from the front.

OPERATION
The Rotor-Router Input Module has no operator controls. The Rotor-Router Output Module has one
twelve position rotary switch associated with each output. The switch is rotated to select one of the
twelve input signals to drive the associated output. For example, if a moving light console is
plugged into input connector number seven, and the fixture to be controlled by that console is
plugged into output number eleven, then the rotary switch associated with output eleven should be
set to seven.
Each module has twelve optical isolation circuits within the chassis. Each isolation circuit has its
own power supply, so there are twelve POWER indicators on the front panel. All power indicators
should be on when the module is plugged into AC power.
Each optical isolation circuit has a SIGNAL indicator. When an isolation circuit is configured as
an input (DMX512 signal coming into the Rotor-Router from a console), the signal indicator will
illuminate when a digital signal is detected. When an isolation circuit is configured as an output
(DMX512 signal coming out of the Rotor-Router to control a DMX512 device), the signal indicator
will illuminate when the rotary switch is set to an input that is receiving a digital signal.
NOTE: The signal indicators on the Rotor-Router indicate the presents of a digital signal, not
necessarily a valid DMX512 signal.
LINE TERMINATION
The Rotor-Router has internal 120 ohm termination on each input. The outputs of the Rotor-Router
require termination only when connected to a DMX512 device. The terminator should be placed
on the feed through connector of the final device on each output line. Unused Rotor-Router outputs
do not need to be terminated.
WARNING: Removal of the termination resistors should only be done in rare, specialized cases.
